What are hydrocarbons used for fuel in stoves and air planes?
When hydrocarbons burn, they release a great amount of energy.
What is the importance of enzymes to biological systems?
Enzymes decrease the amount of activation energy required for chemical reactions to occur.
What is the maximum possible amount of product obtained in a chemical reactions?
It is a Theoretical Yield
What is a Protein that speeds up chemical reactions in living things?
Enzymes are a type of protein that catalyse chemical reactions. There are many different types. They speed up the reaction by lowering the activation energy. This is the amount of energy needed to begin the reaction. The proteins that are vital to living things because they speed up chemical reactions are called enzymes. They are catalysts that lower the activation energy of chemical reactions.
How does an enzyme affect human life?
Enzymes facilitate chemical reactions. Many are catalysts that decrease the amount of energy required for or increase the rate of chemical reactions to take place. Many enzymes work by bringing the substrates of a chemical reaction into close proximity and in favorable orientation. They may also allow the chemical reaction to use chemically stored energy (ex. ATP, GTP etc) to power the reaction. Without these enzymes, some of the reactions would be extremely slow or require excessive temperatures to complete.
What are hydrocarbons used for fuel in stoves and air planes?
When hydrocarbons burn, they release a great amount of energy.
What substances does fuel usually contain?
Most fuels are based on hydrocarbons. When hydrocarbons are burned (oxidized), a significant amount of chemical energy is released in the form of heat.
Are exothermic reactions chemical?
Most chemical reactions are exothermic, that is, they release a certain amount of heat as a by-product of the reaction. Endothermic reactions, those which absorb heat, also do occur, but they are more rare. Endothermic reactions are driven by entropy only, whereas exothermic reactions are driven by the energy that is released. The more energy is released, the more easily the reaction will occur.
What is the initial amount?
The starting amount. In chemistry it would be the amount you have before any chemical reactions or changes happen.
True or false activation energy is needed only by chemical reactions that release energy?
true activation energy is the minimum amount of energy needed to start a chemical reaction
In most chemical reactions the amount of product obtained is?
equal to the theoretical yield
What is the role of energy in chemical reations?
All chemical reactions need a certain amount of activation energy to get started.
What is the term for the amount of energy that needs to be added for chemical reactions to start?
activation energy
What is the importance of enzymes to biological systems?
Enzymes decrease the amount of activation energy required for chemical reactions to occur.
What term describes a substance that lowers the amount of energy needed to start a chemical reactions?
Catalyst
What is the maximum possible amount of product obtained in a chemical reactions?
It is a Theoretical Yield
What According to modern chemistry what causes chemical reactions?
A chemical reaction is caused by two compounds colliding. This happen with certain amount of force.
